the locknut is in threaded connection with the nail head end of the mounting screw;
the rubber gasket is sleeved at the top end of the rubber sleeve main body and is positioned between the vehicle body and the antenna.
Preferably, the bottom end of the outer wall of the rubber sleeve main body extends horizontally outwards to form a convex ring, and the top end of the outer wall of the rubber sleeve main body is horizontally concave inwards to form a concave ring; the aperture of the concave ring is equal to the inner diameter of the rubber gasket.
Preferably, a flat gasket sleeved on the mounting screw is arranged between the bottom of the rubber sleeve main body and the nut end of the mounting screw;
a flat gasket sleeved on the rubber sleeve main body is arranged between the bottom of the rubber gasket and the top of the antenna;
a flat gasket sleeved on the mounting screw is arranged between the top of the rubber gasket and the bottom of the vehicle body;
an elastic washer sleeved on the mounting screw is arranged between the locknut and the vehicle body;
and a flat gasket sleeved on the mounting screw is arranged between the elastic washer and the vehicle body.
Preferably, the nut end of the mounting screw is in press contact with the bottom of the rubber sleeve main body;
the convex ring is pressed and contacted with the bottom of the antenna;
the outer diameter of the rubber gasket is larger than that of the rubber sleeve main body.
The utility model has the advantages that: the utility model discloses the vibration that can effectual reduction vehicle antenna received plays positive effect to the environmental suitability that reduces antenna fault rate, improves vehicle antenna, improves the life of antenna.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1-3, the rubber vibration damping device for track traffic vehicle-mounted antenna of the present invention, which connects the vehicle body 5 and the antenna 7, the rubber vibration damping device 20 comprises: the mounting screw comprises a mounting screw 1, a locknut 2, an elastic washer 3, four flat gaskets 4, a rubber washer 6 and a rubber sleeve main body 8.
A through hole is formed in the center of the rubber sleeve main body 8, and the rubber sleeve main body 8 penetrates through the antenna 7 from bottom to top. The nail head end of the mounting screw 1 is inserted into the through hole of the rubber sleeve main body 8 from bottom to top and penetrates through the vehicle body 5. The locknut 2 is connected with the nail head end of the mounting screw 1 in a threaded manner. The rubber gasket 6 is sleeved on the top end of the rubber sleeve main body 8 and is positioned between the vehicle body 5 and the antenna 7.
The bottom end of the outer wall of the rubber sleeve main body 8 extends outwards horizontally to form a convex ring 81, and the top end of the outer wall of the rubber sleeve main body 8 is concave horizontally to form a concave ring 82; the diameter of the hole of the concave ring 82 is equal to the inner diameter of the rubber gasket 6.
A flat gasket 4 sleeved on the mounting screw 1 is arranged between the bottom of the rubber sleeve main body 8 and the nut end of the mounting screw 1. A flat gasket 4 sleeved on the rubber sleeve main body 8 is arranged between the bottom of the rubber gasket 6 and the top of the antenna 7. A flat gasket 4 sleeved on the mounting screw 1 is arranged between the top of the rubber gasket 6 and the bottom of the vehicle body 5.
